O, The Oprah Magazine, in partnership with Zappos.com is going on a kindness mission to spread the love and make the world a friendlier place. Each month, we'll be giving you a brand new kindness challenge. This month's challenge – Pledge to Read!

O challenges readers to read a book from the O summer reading list. When 50,000 people pledge to read, O will donate $5,000 to Teach for America
